Breast cancer is an increasingly common disease in women. It is almost always treated with surgery. The type of surgical procedure depends on the location, size and prevalence of the malignant process. After the operation, the question of quality of life arises. Quality of life is basically a subjective impression and satisfaction with certain segments of life, whether it is physical fitness and appearance, social component or cognitive functioning on a daily basis, every person should strive to improve quality of life and take care of their health. Different events or illness become the starting point for self-assessment of quality of life. The diagnosis of a breast tumor is followed by a demanding, exhausting period of life that changes fundamentally. In our society, breasts are a reflection of femininity. Depending on the type of breast cancer surgery, both the ultimate aesthetic and the acceptance of the new look depend. The disease affects not only the physical and psychological aspect of life, but can also affect the social aspect. The aim of this study was to examine the quality of life after breast surgery, depending on the type of surgery, whether it is a sparing operation or the removal of the entire breast (mastectomy) with or without reconstruction of prostheses and back muscle. Advances in medicine and the possibility of reconstruction work in favor not only of satisfaction with appearance, but also of everyday functioning, with as few limitations as possible in the physical, mental, emotional and social aspects. The study involved subjects with breast cancer who had one of the above operations in the treatment. The results of a study conducted on 100 subjects at the Clinical Hospital Center Sestre Milosrdnice, at the Clinic for Tumors, are presented. There is no difference in the assessment of quality of life depending on the type of surgery.
